Best way of removing brown sticky stuff on paint inside engine bay?

[stellardude]

Pictures below show it. Its not rust, its like this caked on stuff of like dirt or something. I tried an engine degreeser but it didn't work. What should i do?

Brake cleaner, it also works better then engine degreaser. Just don't do it on your driveway, because all that brow stickystuff will end up on your driveway.

yea, simple green or purple power degreaser (it comes in a jug). let it soak in that stuff for a few minutes, then scrub and rinse.
